Designing homes to conserve energy and use it efficiently, from sources that cause least environmental harm.

Standby mode

Leaving appliances in standby mode can consume a significant amount of energy.

Many appliances have a standby mode during which they are not providing useful output but still consume energy. Some appliances use standby power to light an LED display while some are waiting for remote control signals to tell them to start operating, or are sending and/or receiving signals to other appliances such as home automation systems.

Standby and baseload consumption together can account for 10% of the energy used in an average house around $200 per house per year (all electric house @ $0.28/kWh).

Standby power can be saved by turning appliances off at the wall if they are not being used.

Standby power is considered in the calculation of Minimum Energy Performance Standards (MEPS) and Energy Star. For example, to qualify for an Energy Star rating, a television or DVD player must use no more than 1 watt in standby mode.
